Multiaxial stress effects on fatigue behavior of filled natural rubber
This work explores multiaxial stress effects on fatigue crack nucleation and growth in filled natural rubber based on experiments using short thin-walled cylindrical specimens subjected to axial and twist displacements. Cyclic stress–strain response exhibits significant initial softening relative to the monotonic response, followed by a more gradual additional softening. Irreversible breakage o...
متن کاملMultiaxial high-cycle fatigue criterion and life prediction for metals
A new high-cycle fatigue criterion based on the critical plane approach is proposed in this paper. Unlike most of the other multiaxial fatigue criteria based on the critical plane approach, the critical plane is directly correlated with the fatigue fracture plane. The proposed criterion has a wide range of applicability from very ductile metals to extremely brittle metals. Mean stress effect is...
متن کاملPrediction of Fatigue Life in Notched Specimens Using Multiaxial Fatigue Criteria
In this research, the effects of notch shape on the fatigue strength of 2024-T3 aluminum alloy notched specimens have been studied using experimental and multiaxial fatigue analysis. For this purpose, four set of specimens with different notch shape were prepared and then fatigue tests were carried out at various cyclic longitudinal load levels. Load controlled fatigue tests of mentioned specim...
متن کاملThe Effect of Maximum Strain on Fatigue Life Prediction for Natural Rubber Material
Fatigue life prediction and evaluation are the key technologies to assure the safety and reliability of automotive rubber components. The objective of this study is to develop the fatigue analysis process for vulcanized rubber components, which is applicable to predict fatigue life at initial product design step. Fatigue life prediction methodology of vulcanized natural rubber was proposed by i...
متن کاملA New Energy-Critical Plane Damage Parameter for Multiaxial Fatigue Life Prediction of Turbine Blades
As one of fracture critical components of an aircraft engine, accurate life prediction of a turbine blade to disk attachment is significant for ensuring the engine structural integrity and reliability. Fatigue failure of a turbine blade is often caused under multiaxial cyclic loadings at high temperatures. In this paper, considering different failure types, a new energy-critical plane damage pa...
